Themler use Bootstrap 3 that is quite old. Also Themler use outdated technologies and SEO practices. It's partly support Joomla 4 (with a lot of bugs that not solving), but Joomla 4 itself use Bootstrap 5. So, Joomla 4 support = Bootstrap 5 support.
All this old things will slow down your website and SEO rank.
For now Themler look like abandoned software without future.
Nicepage is completely different software and can't replace Themler. So there is no alternative... only to find another template builder.
And if you want to try Nicepage, there is open question: can you trust to this company? BTW, there is not possible to upgrade Nicepage theme from Joomla 3 to Joomla 4.... you need to re-export theme for Joomla 4 and add all content from web plugin manually... while almost all other developers give you easy way to upgrade.
Same for Themler, you can't to upgrade from Joomla 3 to Joomla 4... you need to re-create template manually.
Most voted and most wanted features was not implemented in Nicepage since 2-3 years. So it's looks like Nicepage stuck in a wrong way.
Please vote for this topic: Themler 2.0 with Bootstrap 5 and support only two CMS: Joomla 4 and WordPress 5
